I've changed the motherboard and cpu in my pc and I'm not sure wether I have have to buy a new copy of windows when I reinstall it. I know that the computer is defined by its motherboard and when I change it, it's pretty much a new computer. So when I reinstall windows will I need to buy a new copy of windows 7 or can I use the disc and code I have for my original version of windows 7.
(I've checked and I have the oem version of windows).
